A 3-axis DRO customized kit featuring glass linear scales and a digital readout with multilingual support, memory capability, power-off memory, and additional functions like circumference drilling and oblique line drilling. It is designed to fit various milling and turning applications, with selectable axis travel and a built-in calculator for on-the-fly calculations.
3 Axis DRO LCD Screen for Bridgeport
Brand: Baykunl. A 3-axis digital readout designed for Bridgeport-style mills and lathes, featuring a 7-inch LCD screen, an integrated RPM sensor, and a robust 34-bit core chip with 64 MB RAM. It supports MM/INCH, memory, power-off memory, bevel processing, and other advanced functions for precise multi-axis positioning and workflow efficiency.
3 Axis DRO With Magnetic Scales
Brand: Baykunl. This 3-axis DRO system includes customized magnetic scales, a high-performance core, SDM memory, and power-off memory. It provides efficient control across milling and lathe setups with similar features to the other Baykunl models, emphasizing data reliability and ease of operation for complex machining tasks.
TOAUTO 2 Axis DRO Display
Brand: TOAUTO. A 2-axis DRO with a customizable travel length (100–1000 mm), offering 5 μm resolution options and a robust metal housing. It includes multi-language support, memory, and a calculator for practical use in coordinate referencing during milling or lathing tasks.
Buying Guide
Key considerations when choosing a DRO for milling machines include measuring range and axis coverage. Determine whether a 2-axis or 3-axis system best fits your workflow, and assess whether you need custom-length scales or standard kits. Readability matters; a large remote display reduces operator fatigue and improves setup speed. Look for memory functions, power-off memory, and advanced features like circumference drilling or oblique line drilling when performing repetitive operations. Consider compatibility with your machine’s control system and the ease of installation, including mounting options and available accessories. Finally, evaluate build quality—aluminum or robust plastic housings, shielded cables, and reliable sensors help ensure long-term accuracy in a busy shop.
